It will be seen that upon rotation of the shaft 21 the respective paddle members 26 come in contact with the ore in the trough 8 and force the ore forwardly. As the paddles revolve the spring blades to which they are attached are pushed back by the resistance of the ore so that when a paddle reaches the mouth portion 28 of the stacker its spring blade straightens out, thereby vigorously impelling the ore out of the stacker. The force with which the ore is ejected is also dependent upon the speed of rotation of the shaft 21 and attached paddlemembers. By

increasing the speed, the force of ejection of the ore will be considerably increased.

Means are provided for holding the dirt or ore back until the paddles can compress it sufficiently to prevent it scattering to any substantial extentwhen it is ejected. One formof means which may be employed for this purpose is shown in the accompanying drawings and may be constructed substantially as follows:

A series of baffles 29 are hinged under the discharge end 28 of the trough 8. Each baflle is shown as projecting upwardly from a corresponding arm 30. pivotally mounted in a bracket 31 mounted on a cross bar 32 on the underside of the trough. As shown, the respective baffle members 29 project upwardly in front of the trough floor 8 and into the path of the ore, said members being biased to, ore obstructing position by springs Three bafi les are shown, one for each series of the paddle members 26. As a paddle rotates and forces the ore forwardly the baffle retards the ore until 'th'e'compression of the ore provides sufficient pressure on the baffle to overcome the action of the spring 33, whereupon the baffle is forced downwardly until the material passes over it, and the baffle is then returned to its normal position by said spring. 1

Through the ore discharging means which I have disclosed I find that the ore may be ejected to great heights, heights as great as fifty feet having been obtained. Thus, large volumes of ore may be readily stacked without necessitating shifting of the apparatus to different positions.

The term ore specification and claims is not employed in any restricted sense but is intended to cover material of allied or similar character such asclay, dirt, or the like.

The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intenthe features shown and described or portions thereof, but recognize thatvarious structural tion, in the use of such terms and expressions,

of excluding any mechanicalequivalents of as used. throughout the modifications are possible within the scope of the invention claimed.

What I claim is:

1. In an apparatus of the character described, a trough adapted to receive ore from a conveyor, means comprising a series of rotatable paddle members for ejecting the ore from said trough, and bafiie means providing for compression of the ore by said paddle members.

. 2. In an apparatus of the character described, the combination of a trough adapted to-receive ore from a conveyor, a plurality of sets of paddle members for ejecting ore fromsaid trough, and a plurality of baffle members, one for each of said sets of paddle members, for resisting discharge of the ore said paddle members.

3. In an apparatus of the character described, the combination of a trough adapted to receive ore from a conveyor, means comprising a series of paddle members for ejecting ore from said trough, and bafile means providing for compression of the ore by said paddle members, said baffle means yielding in response to the action of said paddle members to permit the discharge of the ore.

4:. In an apparatus of the character described, a trough adapted to receive ore from a conveyor, movable means for discharging ore from said trough, baflle means for resisting movement ofthe ore until the latter is compressed to a'given extent, said baflie means yielding after such compression of the 'ore to permit the ore to be readily discharged.

5. In an apparatus of the character described, a trough adapted to receive ore from a conveyor, movable means for discharging ore from said trough, baflie means for resisting movement of the ore until the latter is compressed to a given extent, said baflie 7 means yielding after such compression of the March, 1929.
